Answer:
7.92 miles (aprox.)
Step-by-step explanation:
1 hour = 60 minutes
19mph = 19miles/hour = 19miles/60 minutes
Proportions:
19 miles ⇔ 60 minutes
W miles ⇔ 25 minutes
W = 19*25/60
W = 7.92 miles (aprox)
A2=a1*(-1)=8*(-1)= - 8
a3= (-8)* (-1)= 8
.....................................
a(n)= a(n-1)* (-1)
14. 7+3=10 and 7-3=4 so 7x2=14
